I purchased this during the Diwali season( November 2015) just because it had a huge battery( 3900mAh) with good specifications at the price of 8000 rupees. I wasn’t sure if it would perform well or not. But when I started using it, I was surprised by its performance. It performs very well with almost no lags. Even with the Mediatek processor most of the games are playable without any lags. While playing super HD games, I notice frame drops here and there but come on at 8000 rupees price point it is acceptable. And with the 2GB of ram, multi tasking is great. I don’t personally like Vibe UI, so I use Google now launcher. The best part is the battery, it is awesome in battery backup department and the charging time is good too( Due to 5.2V/2Amp charger bundled in the box)
Best things is that Screen Protector and good looking back cover is given in the box already, so no need to buy them separately( saves your 300-400 bucks)
Now talk about some weakness I found in it, first of all the real camera isn’t that good. It is bad, but I feel that it could have been better. Front camera works fine though.
So final verdict is that You should go for it if you are not a Heavy Gamer, No phone is better than this in battery department in this price segment.
I hope I could help.: -)
